Sea cucumber has rich nutritional value and can be used for dietetic therapy and health preservation. In the process of market circulation and storage, sea cucumber is susceptible to quality deterioration due to autolysis and microbial growth, resulting in huge economic losses. Clarifying the...

This paper analyzed the data of pesticide and veterinary drug residues in food reported to China from 2015 to 2019 based on the European Union's rapid alert system for food and feed (RASFF) data, so as to reflect the quality and safety status of China's export food. The safety status of food,...

Traditional thermal sterilization has been demonstrated to cause adverse effects on food quality, resulting in undesired consequences including color changes, odor generation and nutritional loss. The non-thermal sterilization technology is a new processing technology that has been applied in the...

Objective: To evaluate the accuracy of 5 kinds of rapid detection kits based on immune principle in the market for detecting 7 kinds of sulfonamide veterinary drug residues. Methods The 5 kinds of rapid detection kits and GB/T 21316-2007 Determination of sulfonamide residues in food of animal...

An enzyme inhibition method was established and used for multi-residue detection of β-lactamase inhibitors in milk. For sample preparation, the protein was precipitated with acetonitrile and the fat was removed with n-hexane. The matrix-matched external standard method was used for quantification,...
